Yes it does. The weirdest thing is that I can kill the other programs running in the foreground and background if I don't Touch the crash window. Once I touch the crash window, the only thing I can do is ctl+alt+del and restart. I can't start any task, including the task manager even if I don't touch the crash window.

Tasks start, but do not initialize. Everything seems to be hung. I've given the system time to resolve things on it's own a few times, but that didn't help.

What could possibly cause the thermal controller to crash, and if I click the OK button on the crash screen, the system locks up?

This only happens when the computer goes to sleep. Could this be thermal related?

Mine does this too but its a 50/50 chance not 100% of the time. It will not respond and require a hard restart. It used to work fine but in the last month or so it started doing it. I just disabled sleep mode and made sure my monitor was set to shut off. A fresh OS install didn't make it go away.

All you can really do is try reinstalling ACC a few times and call Dell.They will replace the MIO board if they think thats it. I called them yesterday about mine and they didnt even bother to check it once they saw the failed usb warning and just sent me a new one. All the ones I have had seemed to degrade over time to the point they stopped working. They will start getting a USB has failed warning or all the lights will stop working and the fans will go to 100%. At that point the boards are no more:(

But this doesnt mean its the same issue as yours. Maybe your system is crashing coming out of sleep and you are just seeing the thermal warning because of the system crash. Heck maybe it isnt my MIO board doing it ether but I figure its a good place to start.

I also had this issue back when I first got my 980X CPU. The BIOS at the time didnt support it. When the new BIOS came out the crash from sleep went away.

I will find out for sure tomorrow when I install the new board. I will let you know if it solves the sleep issue for me.

My new board came but they sent me a bad board. It was not working at all. I had 100% fan speed and no lights. I had to put my old board back in. They send them straight to me instead of a tech so I should have another one monday or tuesday.

When I put my old board back in I didnt get the failed USB warning. But now I get two back to back sounds for when a device connects to a USB. I guess its going off and then on or on and then off but hey, no pop up warning and device manager is not showing the failed USB. As for sleep its still not working.
